How to Integrate Replit with OpenAI

This tutorial shows how to connect OpenAI to a Replit project using Replit's built-in AI integration, so you can build AI-powered features without leaving your workspace. 

Notes: 

• The built-in OpenAI integration (Replit-managed) requires a paid Replit plan and bills usage through your Replit credits. 
• When the Agent detects an OpenAI dependency, it will display a confirmation prompt showing "OpenAI (Replit managed)." Click Approve to let Replit handle the API credentials automatically.
• See How to Set Environment Variables in Replit for more on Secrets.
  

1. Sign in at replit.com and open the project you want to add OpenAI to, or click + Create Something New to start a fresh one.
2. In the Agent prompt field, describe what you want to build and mention OpenAI directly - for example: Build a client briefing tool for NEPS Corp that takes a project name and returns a short AI-generated summary using OpenAI. Click the Arrow button to run.
3. The Agent generates your project files and wires up the OpenAI connection. Wait for the build to complete.
4. Click Run to launch your app. Test it in the Webview tab - for example, enter "Q3 Budget Review" as the project name and confirm the AI-generated summary appears correctly.
5. To swap to your own API key at any time, open the Secrets pane from the Tools menu, add a secret named OPENAI_API_KEY, and paste your OpenAI key as the value. The Agent will use your key instead of Replit-managed credentials going forward.
